Unfortunately, I don't know elisp well enough yet to understand the
docstring of `display-buffer-alist'.  It sounds extremely complicated to
display a buffer in a window that has a particular size and position
with the `display-buffer' function.

Is everyone who's programming something in elisp that involves
displaying buffers expected to implement their own window management to
get buffers displayed the way they want them?  What if the users want
the buffers displayed differently than the programmers or use
features that have their own window layouts that are conflicting with
window layouts of other features?


Perhaps there's something I don't understand ...  A window manager like
fvwm2 does not resize and/or reposition and/or remove all or some of the
windows the user has carefully laid out on the display just because the
user decides to display a manual page or an info document, or starts
writing a reply to an email in one of the windows.  What is the point of
emacs destroying the users window layout all the time?
